Title: Ethers of 2-methylol-butene-1-one(3) and polymers thereof
IPC: C07C49/255
Filed: 1955-02-24
Abstract: Aliphatic ethers of 2-methylol-butene-1-one-3, particularly the methyl and ethyl ethers, are polymerized at temperatures of 15-25 DEG C. or by heating at 30-100 DEG  C. at normal pressure. Suitable catalysts are benzoyl, t.-butyl, lauroyl, acetyl, ethyl, acetylbenzoyl, urea, and oleic acid peroxides and t.-butyl hydroperoxide; hydrogen peroxide alone or together with organic peracids or peroxyacids, e.g. performic or per acetic acids, or organic acid anhydrides, e.g. acetic or propionic anhydrides; inorganic perborates, e.g. sodium, potassium or lithium perborates in combination with an organic anhydride; sulphoxides of sodium, potassium, lithium and barium, persulphates of alkali metals or ammonium, sulphur dioxide, boric acid anhydride; aluminium chloride, stannic chloride, hydrofluoric acid, boron fluoride or diether compounds thereof, or phosphorus oxychloride; colloidal metal oxides, metal carbonyls and siccatives, such as manganese oleate or resinate. The polymerization may also be accelerated by sunlight or ultra-violet light.  It is preferred to exclude free oxygen by carrying out the process in an atmosphere of nitrogen or carbon dioxide.  In examples: (1) 2-methylol-butene-1-one-3 methyl ether is maintained at 30 DEG  C. in a nitrogen atmosphere for 4 days whereby a transparent resin is formed; (2) the same ether is polymerized at 25 DEG  C. in a nitrogen atmosphere using t.-butyl peroxide as catalyst.ALSO:The invention comprises aliphatic ethers of 2 - methylol - butene - 1 - one - 3, particularly the methyl and ethyl ethers thereof.  The ethers may be prepared by reacting an aliphatic alcohol with 2-methylol-butene-1-one-3 at an elevated temperature in the presence of a strong acid.  The aliphatic alcohols, such as methyl, ethyl, propyl, butyl or allyl alcohol, are preferably used in excess, e.g. 2-6 mols. of the alcohol per mol. of the butenone. Methyl and ethyl alcohol are preferred and mixtures of such alcohols may also be used.  The strong acid may be a mineral acid such as sulphuric, hydrochloric or phosphoric acid, or an aryl sulphonic acid, such as benzene sulphonic acid or p-toluene-sulphonic acid. 0.1-2 per cent of such acids based on the amount of the butenone is sufficient.  On completion of the reaction, the reaction mixture is neutralized with an alkali metal hydroxide, e.g. sodium or potassium hydroxide, or an alkali metal carbonate, e.g. sodium carbonate or bicarbonate, or potassium carbonate or bicarbonate, or ammonia or ammonium carbonate, followed by vacuum distillation during which the excess alcohol and water distil over first.  The ethers may be polymerized to form synthetic resins (see Group IV (a)).  Detailed examples describe the etherification of 2-methylol-butene-1-one-3 with (1) methanol in the presence of conc. sulphuric acid and (2) ethanol in the presence of p-toluene-sulphonic acid.

Title: Method and apparatus for processing filamentary material
Inventor: HOLSCHLAG JERRY BERNARD
IPC: D01H1/00
Filed: 1964-02-10
Abstract: In ring-spinning apparatus, the spindle is driven at a constant rate and the means feeding yarn to the spindle is drawn at a continuously increasing rate, thus compensating for the constantly decreasing diameter of the supply packages and the increasing size of the collected packages.  In the case of a double-order frame, the receiving-spindles in each row are driven by a common endless belt pressed into engagement with the wharves by idlers and trained around pulleys one of which is driven.  Each row of spindles is supplied from two or more superposed rows of packages.  In one form, each of these packages is in a sleeve on a cylindrical support caused by a shaft terminating in a wharve, all the wharves on each row being engaged by an endless belt.  In another form, the yarn is drawn off the packages by feed rolls. The endless belt or the feed rolls are driven at continuously increasing speed through a clutch Fig. 3 (not shown,) comprising balls running on the driving and driven members each have a diametric shaft extending into a slot in a plate which is continuously rotated to vary the angular position of the shafts. The ringrails on each side are reciprocated by pokers linked to a rod connected to a follower running in a groove in a driven eccentric.
